摘要
我们报告了对三体衰变 Y(10860)=> B barB pi、Y(10860) => (B barB* + c.c.) pi 和 Y(10860)=> B* barB* pi 分析的初步结果，其中包括对作为中间道的 Y(10860)=> Zb(10610)+- pi-+ => [B barB*+c.c]+- pi-+ 和 Y(10860)=> Zb(10650)+- pi-+ => [B* barB*]+- pi-+ 衰变的观测。我们测得三体衰变的分支比为 Br(Y(10860)=> [B barB*+c.c.]+- pi-+)=(28.3+-2.9+-4.6)x10^{-3} 和 Br(Y(10860)=> [B* barB*]+- pi-+)=(14.1+-1.9+-2.4)x10^{-3}，并设定了 90% 置信水平上限 Br(Y(10860)=> [B barB]+- pi-+)<4.0x10^{-3}。我们还报告了三体 Y(10860)=>Y(nS)pi+pi- (n=1,2,3) 衰变的振幅分析结果，以及三体 Y(10860)=>hb(mP)pi+pi- (m=1,2) 衰变内部结构的分析结果。这些结果基于 Belle 探测器在接近 Y(10860) 的质心能量处收集的 121.4 1/fb 数据样本。
